| Abstract: | The kinetics of RE (La, Gd, Er, Yb and Y) extraction with sec octylphenoxy acetic acid was investigated using a constant interfacial area cell with laminar flow at 303 K. The natures of the extracted complexes have some effect on the extraction rate which is controlled by the reaction rate of M(III) and extractant molecules at two phase interface for Er(III), Yb(III) and Y(III), by a mixed chemical reaction diffusion for Gd(III) and a diffusion for La(III). The extractant molecules tend to adsorb at the interface. So an interfacial extraction reaction model was derived. |
